its variants (six-ball, seven-ball, and ten-ball) are rotation games but with a smaller ball set and without the point-based scoring. In these games only the namesake number of balls are used, and winning is dependent on being the player who pockets the highest ball in the set, even if it is pocketed before other balls or if the winner pockets no other balls. Strict rotation In strict rotation, also called specific rotation, the balls must be pocketed sequentially, not the first contact on the table. If the lowest ball on the table is struck but a higher ball ends up being pocketed in a combination shot, then that higher ball must be back on the table after the shot; this is not a foul, but merely ends the shooter's turn as if it were a miss. If the lowest-numbered ball is hit first and is pocketed, but another ball also is pocketed, that other ball is spotted immediately, and the shooter's turn continues. In the Philippines In the Philippines, rotation pool is popular, especially among advanced players, although eight-ball, nine-ball and, increasingly, ten-ball, are widely played.
